Product information
Overview
Key Features
- 8 isolated analog inputs: Provides 8 analog inputs for voltage and current signals; thermocouple, resistance thermometer and resistance input ranges are not supported.
- Supported signal ranges: Rated ranges include 1 V to 5 V, -10 V to +10 V, -5 V to +5 V, 0 to 20 mA, -20 mA to +20 mA and 4 mA to 20 mA.
- 16 bit conversion resolution: Maximum resolution with overrange is 16 bit; parameterizable integration time is 10/ 16.67/ 20/ 100 ms.
- Diagnostics and alarms: Has parameterizable diagnostics, diagnostic alarm and limit value alarm for channels 0 and 2, plus a red group error SF LED.
- Isolation and front connection: Analog inputs are isolated from the backplane bus and are not isolated between channels; channel isolation is arranged in groups of 2. The required front connector is 40-pin.
- SIMATIC S7-300 configuration: This spare part is an SM 331 module with single-point grounding (50 V COM.) and a 1x 40-pole connection.
